With the progress of human science and technology and civilization, in the process of exploring Mars, human beings contribute to the development of cutting-edge technology industry and can better promote the construction of human civilization. In addition, with the continuous increase of the earth's population, the continuous destruction of the earth's natural ecological environment, the frequent occurrence of natural disasters, the imminent depletion of fossil energy, environmental pollution, garbage siege and other adverse factors, the continuation of human civilization will face greater threats. However, if humans can be immigrated to another planet, it will avoid the destruction of the earth and lead to human extinction. Therefore, it is necessary to determine whether Mars has a habitable environment. Based on the above background, the author designed and developed a science fiction game based on the PBR sub-era process. The game explores the mysteries of Mars from a first-person perspective. The game is designed and produced based on real Martian data records. Through highly refined game models and environmental simulations, players are provided with a real Martian environment. In the game, players play as a Mars explorer, using a variety of probes, base equipment and vehicles to explore to complete Mars missions to achieve survival and research on Mars. The tasks in the game fully consider the needs of science education and the players' fun and challenge. In the game, players need to make reasonable plans and complete various tasks according to the real Mars scientific data and theory. For example, looking for lost Mars rover, maintenance base facilities, etc., players can also enjoy the real life experience of Mars in the game.
